Yeah, Stella Artois, Jupiler and Maes are the three most popular cheap-and-cheerful 'everyday' beers. The relative popularity of them is very regional, here it's very much Stella Artois followed by Jupiler. You'll actually find it quite hard to get Maes on draught here.
Jupiler I can take or leave, it's not unpleasant, but I just find it quite bland. Since you were in Belgium they changed the Maes recipe and made it slightly stronger, like Stella Artois and Jupiler it's now 5.2% abv. It also has a slightly more malty taste. Like you I prefer Maes to Jupiler, but of the three of them, my favourite is Stella Artois.
